Oh absolutely.
In terms of pocket movement - I'd say in this order:
1)Improviser
2)Strong Arm
3)Field General
Improviser:
These guys are basically the "West Coast" type from the previous maddens. While they don't mind throwing the ball, they usually have above average speed for a QB and make use of it occasionally on a scramble when the defense is napping. Like Scramblers, if they can't find themselves getting away from the pressure - they'll preform a "Throw on the Run".
Strong Arm:
These AI gentlemen LOVE showcasing that Rocket arm. They'll usually favor throwing the ball on Medium/Deep routes over anything else (I seen a SA guy just air it up for 30+yd shot on like 2nd/short numerous times).....they'll be "Balanced" in QB style and one run when the yardage is short or as a last resort.
Field Geneal:
These men just throw the ball, and do it fairly well as they usually have good Short & Medium Accuracy attributes.The guys tend to rarely run - as 9/10 times they have "Pocket" as their QB style.
Again, the QB Style & Sense Pressure together give the AI QB most of their "character" in terms of how they respond to the defense around them.
